Definitions

  • the present invention relates to a fluorescent coating.
  • the present invention relates to a fluorescent coating comprising hollow polymer particles which scatter ultraviolet light and shorter wavelength visible light.
  • the present invention also relates to a method for improving the appearance of fluorescent coatings through the use of such hollow polymer particles.
  • coating includes single layer coatings and multilayer coatings such as those consisting of a basecoat made from a basecoat composition and an over-laying coating layer made from a coating composition.
  • fluorescent coatings are coatings which contain a fluorescent additive, such as pigment and dye, and include but are not limited to paints, inks, leather coatings, adhesives, films and the like.
  • Fluorescent coatings e.g. fluorescent paints and inks
  • Fluorescent coatings are aesthetically desirable in certain applications such as, for example, where safety or decorative purposes are important because of the high degree of visibility generated by the intensity of the fluorescent pigment colours.
  • These fluorescent pigments exhibit their bright colours under daylight conditions as well as under fluorescent and mercury lamps.
  • the appearance of fluorescent coatings is the result of the absorption and re-emission of light by the fluorescing pigment.
  • a problem associated with fluorescent coatings has been their poor covering power. In this regard, light tends to pass through the fluorescent coatings and is absorbed by the substrate reducing the brightness of the coated article.
  • Conventional light scattering pigments such as for example, titanium dioxide, zinc oxide, zinc sulfide, zinc carbonate, kaolin and lithopone can increase the covering or hiding power of coatings.
  • pigments when such pigments are incorporated into fluorescent coatings the added whiteness only detracts from the desired high chroma of the fluorescent coating.
  • JP-A-63131637 teaches the use of hollow glass powders or glass balloons in a fluorescent paint or ink.
  • the hollow glass powders are incorporated into the fluorescent paint at a concentration of from about 5% to 20 % by weight and have an average particle size diameter of about 20 microns to 50 microns and a wall thickness of several microns.
  • fluorescent paints containing these hollow glass powders can eliminate the need for a white basecoat.
  • GB-A-2224737 teaches a water-based ink composition for writing on neon boards comprising at least 30% by weight water; 0.5-50% by weight hollow resin particles; 0.5-30% by weight resin which is film-forming at room temperature; and 0.5-25% dry weight of aqueous emulsion of at least one nonvolatile or only slightly volatile liquid selected from aliphatic carboxylic acid esters, higher hydrocarbons and higher alcohols. Markings from this ink composition on transparent glass or plastic panels are intensely brightened when a surface receives incident light perpendicular into the panel.

  • At least one hollow polymer particle which scatters ultraviolet light and shorter wavelength visible light in a coating comprising at least one fluorescent additive for enhancing the fluorescence of the coating.
  • the coating comprises a basecoat composition and a coating composition wherein either the basecoat composition or the coating composition comprises the at least one hollow polymer particle.
  • the coating comprises a basecoat composition and a coating composition wherein either the basecoat composition or the coating composition comprises the least one fluorescent additive.
  • the at least one hollow polymer particle and the at least one fluorescent additive may both be present in the coating composition.
  • the at least one hollow polymer particle may be present in the basecoat composition and the at least one fluorescent additive may be present in the coating composition.
  • both the coating composition and the basecoat composition may comprise the at least one hollow polymer particle and the at least one fluorescent additive.
  • the hollow polymer particle comprises from about 1% by weight to about 90% by weight of the coating composition solids, basecoat solids or total coating solids. More preferably, the hollow polymer particle comprises from about 5% by weight to about 50% by weight of the coating composition solids, basecoat solids or total coating solids.
  • the hollow polymer particles have a particle size diameter of from about 0.07 microns to about 4.5 microns and a void diameter of from about 0.05 microns to about 3.0 microns.
  • the hollow polymer particles have a particle size diameter of from about 0.1 micron to about 3.5 microns.
  • the coating is either a paint or an ink.
  • the at least one fluorescent additive absorbs light with a wavelength less than about 500 nanometers.
  • the fluorescent additive is orange, yellow, red, blue, green, pyranine, fluorescein, or Rhodomine B pigment.
  • coating components such as, for example, pigments, binders, vehicles, extenders, dispersants, surfactants, coalescents, wetting agents, rheology modifiers, thickeners, drying retarders, antifoaming agents, colorants, waxes, preservatives, heat stabilizers, solvents, anti-skinning agents, driers and the like may be used in the coatings of the present invention.
  • the present invention therefore provides a method for improving the fluorescence of a coating composition containing at least one fluorescent additive comprising adding to the coating composition at least one type of hollow polymer particle which scatters ultraviolet light and shorter wavelength visible light in an effective amount to enhance the fluorescence of the coating composition.
  • the present invention also provides a method for improving the fluorescence of a coating comprising a basecoat composition and a coating composition containing at least one fluorescent additive, the method comprising adding to the basecoat composition at least one type of hollow polymer particle which scatters ultraviolet light and shorter wavelength visible light in an effective amount to enhance the fluorescence of the coating composition.
  • the present invention also provides a basecoat composition for a coating which comprises at least one fluorescent additive which absorbs light with a wavelength less than about 500 nanometers and fluoresces the light, wherein the basecoat comprises at least one hollow polymer particle which scatters ultraviolet light and shorter wavelength visible light.
  • the present invention may therefore be practiced by:
  • the hollow polymer particle according to the present invention i.e. hollow polymer particles which do not substantially absorb near ultraviolet light and shorter wavelength visible light
  • the hollow polymer particle may be employed as an additive in a fluorescent coating, as an additive in a basecoat onto which a conventional fluorescent coating is applied, or as an additive in both a fluorescent coating and a basecoat onto which the fluorescent coating is applied.

  • the hollow polymer particles which are useful in this invention may be made in accordance with, and having the properties disclosed in, the teachings of US-A-3,784,391, US-A-4,798,691, US-A-4,908,271, US-A-4,910,229, US-A-4,972,000, JP-A-60/223873, JP-A-61/62510, JP-A-61/66710, JP-A-61/86941, JP-A-62/127336, JP-A-62/156387, JP-A-01/185311 and JP-A-02/140272.
  • the preferred hollow polymer particles and their method of manufacture are disclosed in US-A-4,427,836, US-A-4,469,825, US-A-4,594,363 and US-A-4,880,842.
  • the hollow polymer particles according to the present invention provide hiding or covering power to coatings in much the same manner as opacifying pigments, such as for example titanium dioxide (TiO2) and zinc oxide, they also exhibit a significantly different behavior when a coating containing them is exposed to ultraviolet light (UV).
  • opacifying pigments such as for example titanium dioxide (TiO2) and zinc oxide
  • UV ultraviolet light
  • the hollow polymer particles of the present invention do not substantially absorb light which normally excites fluorescent pigments, such as ultraviolet light and shorter wavelength visible light.
  • the hollow polymer particles of the present invention both permit a greater flux of ultraviolet light and shorter wavelength visible light in a coating and, in the case of a coating which contains a fluorescent additive, improve the fluorescence of the coating compared with conventional opacifying pigments.
  • fluorescent paints formulated with titanium dioxide as an opacifying pigment and paints formulated with hollow polymer particles at concentrations designed to match the visible light scattering of the conventional paint are visually similar.
  • the paints formulated with the hollow polymer particles exhibit a much higher degree of fluorescence.
  • the phenomenon is applicable with any fluorescent additive, such as for example pigments and dyes, which are initially excited by ultraviolet light and visible light with a wavelength less than about 500 nanometers (nm), preferably less than about 450 nanometers.
  • the fluorescent pigments and dyes which exhibit this effect in coatings containing the hollow polymer particles include, for example, DayGloTM Fire Orange, DayGloTM Saturn Yellow, DayGloTM Rocket Red, DayGloTM Horizon Blue, pyranine, fluorescein, Rhodomine B and the like. (DayGlo is a trademark of the DayGlo Corporation).
  • the hollow polymer particles according to the present invention are useful in fluorescent coatings at levels of from about 1% by weight to about 90% by weight of the formulation solids. Generally, levels of less than about 1% by weight of the formulation solids do not provide sufficient opacity. Generally, levels greater than about 90% by weight of the formulation solids interfere with film formation. Levels of hollow polymer particles from about 5% by weight to about 50% by weight of the formulation solids are preferred.
  • the hollow polymer particles useful in fluorescent coatings have particle size diameters of from about 0.07 microns to about 4.5 microns, preferably from about 0.1 microns to about 3.5 microns. Hollow polymer particles with a void diameter of from about 0.05 microns to about 3.0 microns are preferred.
  • Fluorescence spectra of the paint specimens were obtained using Spex Fluorolog II® Spectrofluorometer used in conjunction with a Spex Model DM1B Data Analyzer.
  • a 150 Watt Xenon lamp was used for the excitation source for ultraviolet and visible wavelength regions.
  • Steady state emission spectra were obtained by holding the excitation wavelength constant while scanning the emission at longer wavelengths.
  • Emitted light was detected using a photomultiplier with an operating voltage of -900 volts and a Spex Model DM102 Photon Counting Acquisition Module. The intensity (measured in photons per second) was recorded at intervals of 0.5 nanometers.
  • Paint specimens were examined using front face illumination: the exciting light impinged upon the paint squares at an angle roughly 45° to the normal of the sample surface, and the signal was collected at 22° relative to the excitation source. Slits were varied between sample sets from 0.5 mm to 1.25 mm as necessary such that the detected signal was kept in the linear range of the photomultiplier tube response.
  • a steady state emission spectrum was collected for each paint sample using an ultraviolet and visible wavelength. From each spectrum, the wavelength at which the maximum intensity occurred and the corresponding intensity at this wavelength (I max ) was determined. Data were collected successively in pairs, with each pair consisting of the hollow polymer particle paint (basecoat or fluorescent coating) and its TiO2 control.
  • the reported fluorescence enhancement is computed as the ratio of the measured maximum intensity of the hollow polymer particle paints samples to the maximum intensity of the TiO2 controls at the same maximum wavelength: I max(hollow polymer) /I max (TiO2) .
  • This intensity ratio was measured for both ultraviolet excitation (375 nm) and visible excitation (500 nm). These wavelengths were chosen as typical for the spectral regions of interest.
  • Formulations 2, 3, 4, 5 and 6 were drawn down side by side with Formulation 1 to minimize film thickness differences with a 17.78 x 10 ⁇ 2 mm (7 mil) Dow bar on Leneta 5C opacity charts and dried at 50% relative humidity and 21.1°C (70°F) overnight.
  • Contrast ratios were determined by the ratio of the reflectance of each coating over the black portion of the opacity chart to the reflectance of each coating over the white portion of the opacity chart as measured by a Pacific Scientific Colorgard® 45°/0° Reflectometer. Relative contrast ratios were then determined by the ratio of the contrast ratio of the comparative paints (Comparative Formulations 2-6) to the contrast ratio of Formulation 1. The results are also reported in Table 2.1.
  • the TiO2 level at which the plot of the relative contrast ratio versus TiO2 level for Comparative Formulations 2-6 equals unity (1.000) is the point of approximately equal opacity between Formulation 1 (containing only hollow particles) and a formulation containing TiO2. This point corresponds to a level of 2.70 weight % TiO2 slurry.
  • 156.5 grams of Comparative Formulation 2 and 245.6 grams of Comparative Formulation 3 were blended to give COMPARATIVE FORMULATION 7 (no hollow polymer particles).
  • Colorants were added to equal volume aliquots of Formulation 1 and Formulation 7 according to levels in Table 3.1.
  • Formulations 1 and 7 were each drawn down several times with a wire wound rod on black vinyl opacity charts to build a thick layer of paint to ensure good opacity. The draw downs were dried at 50% relative humidity and 21.1°C (70°F) overnight. Both formulations were then coated with commercial fluorescent paints using a 17.78 x 10 ⁇ 2mm (7 mil) Dow bar. See Table 4.1. The drawdowns were then dried at 50% relative humidity and 21.1°C (70°F) overnight.
  • the predispersed fluorescent pigment and then the emulsified wax were added and mixed.
  • the opacifying pigment either predispersed TiO2 slurry or hollow polymer particles
  • water was added and the fluorescent ink was mixed for an additional 15 minutes.
  • Each fluorescent ink containing hollow polymer particles was drawn down with a #6 wire wound rod on coated clay, bleached white sealed paper and Kraft paper side-by-side with its respective TiO2 control fluorescent ink.
  • I max ratios greater than 1.0 indicate enhanced fluorescence.
